I'M GETTING READY TO TAKE THE PTCB NEXT MONTH. MY QUESTION IS: HOW DO I KNOW WHAT FORMULA TO USE WHEN SOLVING WORD PROBLEMS? I CAN DO THE MATH, BUT I'M HAVING PROBLEMS KNOWING WHICH FORMULA'S TO PLUG THE PROBLEM INTO. SO HOW DO I KNOW WHICH FORMULA TO USE?

This question comes up often. The answer is kind of a long one, so I wrote an article and posted it on eZine. Click here to read it (opens in another window)and I hope it helps you to understand how to approach the problems better.
